Whats the difference between regular Pokemon, shiny Pokemon, and Shadow Pokemon?

Question

So whats the difference between regular, shiny and shadow Pokemon? I have a shiny Emboar and Charizard, but I dont think theres much difference between the stats. Thx for answers!

Answer 1

Stats:

In Generation II, being Shiny is determined by a Pokémon's IVs. If a Pokémon's Speed, Defense, and Special IVs are all 10, and its Attack IV is 2, 3, 6, 7, 10, 11, 14 or 15, it will be Shiny. Because of this, a Shiny Pokémon traded to a Generation I game and then traded back to Generation II will retain its Shininess, and a Pokémon obtained in Generation I whose IVs meet the requirements for Shininess will also become Shiny when traded to Generation II.

Since the HP IV is calculated from the other four IVs, a Shiny Pokémon's HP IV will always be either 0 or 8. Shiny Pokémon are generally above average in terms of IVs, but only slightly.”

This means the stats determine shininess, but only in R/B/Y/G/S/C.

In other generations, Shinies and Normal Pokemon have the same chance of having good stats.

Now, for shadow Pokémon. I don’t know if you are talking about GO or the other games they are in, so I’ll include both.

A Shadow Pokémon, when encountered, is generated in the same way that a wild Pokémon is generated in the Generation III games, with its personality value and individual values generated together and no effort values. Shadow Pokémon don't have a set Nature or a set gender, but once encountered, the personality value, Nature and IVs are saved to the memory for the Shadow Monitor to be able to keep track of their exact status and location. This means that once a Shadow Pokémon is encountered for the first time, its Nature, IVs and gender will remain the same for the rest of the game, even if the player fails to capture it or is forced to re-battle it later.”

This implies that being shadow does not decrease or increase stats.

In Pokémon GO, they have a 20% increase to attack power but a 20% decrease to their defense

Answer 2

A Shiny Pokémon (Japanese: 光るポケモン Shiny Pokémon), previously officially known as alternate coloration or rare coloration (Japanese: 色違い differently colored), and called Color Pokémon in Pokémon Stadium 2, is a specific Pokémon with different coloration to what is usual for its species. It is one of the many differences that a Pokémon can have within its species.

The term "Shiny Pokémon" was first created by fans to refer to the sparkling sound effect and animation made at the start of an encounter with one in the games. Eventually, this term fell into official usage in Generation IV, used on promotional material promoting Shiny event Pokémon. The term Shiny Pokémon was first used in-game in Pokémon Black and White in Nimbasa City.

Form differences, such as that of Shellos and Gastrodon, are not normal/Shiny variations of one another, but the individual forms can be Shiny.

Shiny Pokémon were introduced in the Generation II games. When a Shiny Pokémon appears in the wild or from its Poké Ball, it is surrounded by a flash of stars or light, which is accompanied by a pinging sound effect.

Shadow Pokémon (Japanese: ダークポケモン Dark Pokémon) are Pokémon that are being used for wrongful acts because they had the doors to their hearts shut artificially, a process created and carried out by Cipher in the Orre region. Collecting Shadow Pokémon through snagging and restoring them to normal by purifying them is the main goal of Pokémon Colosseum and Pokémon XD: Gale of Darkness.

The Trainer of a Shadow Pokémon cannot do any of the following with it until it is purified:
Level it up (when it is purified, it gains all the exp. accumulated as a Shadow Pokémon, which is only when its Heart Gauge is less than three bars full).
Evolve it (evolves when gaining exp.)
Use a Rare Candy on it.
Change the order of its moves.
Delete its moves.
Use a TM on it.
Give it a nickname (due to not having an OT or ID).
Trade it.
Participate in Battle Mode with it.
Enter it in battles at Phenac Stadium.
Enter it in battles at Orre Colosseum.
Shadow Pokémon are also unable to gain effort values from battling, although vitamins can still be used on them.
